ELECTRIC WINDING AND SETTING CLOCK.

SPECIFICATION forming part of Letters Patent No. 526,720, dated October2, 1894.

Application filed October 3, 1893. Serial No. 487.068. (No model.)

T0 at whom it may concern.-

Be it known that I, HENRY LORIOT, a resident of the city, county, andState of New York, have invented certain new and useful Improvements inClocks, of which the following is a specification.

My present invention relates to that class of clocks which aresynchronized periodically from a central or controlling clock by meansof an electric current, and has for its object to perform the operationsof winding and synchronizing the clocks by the same electric impulse,thus dispensing with individual batteries for winding each clock.

To this end my invention consists in connecting the synchronizing magnetand the winding motor of a clock or aseries of clocks in circuit so thatthey may be actuated by the same electric impulse.

My invention further consists in certain improvements in synchronizingdevices for clocks whereby a prolonged impulse may be sent through thesynchronizing magnet without stopping the clock.

My invention is equally applicable to electrically propelled clocks.

Hitherto it has been customary to connect the synchronizing magnets of aseries of clocks in the same circuit, and to wind each clock of theseries by means of a motor in an independent local battery circuit. Ithas also been proposed to Wind and synchronize a series of clocks from acontrolling clock by means of a single wire. In this arrangement thesynchronizing devices were normally in circuit, and the winding motorswere switched in at predetermined times for ashort period, thesynchronizing devices being cut out while the winding was beingeffected. By my invention I dispense with these complications andproduce an extremely simple device entirely adequate to perform all theoperations of synchronizing and winding.

I attain the object of my invention by the mechanism illustrated in theaccompanying drawing, which shows my improvements applied to an ordinaryform of self-winding clock.

In the drawing A is any suitable electric motor serving through themedium of the train of gearsv 1, 2, 3, 4, 5, 6, 7, 8, and 9,to wind themain spring of the clock contained within the going barrel B.

O is the synchronizing magnet, and at its armature. The armature a iscarried on one end of a lover I) pivoted at c and carrying at its otherend a pivoted lever d. This pivoted lever d is normally held against thestop 6 by a springf. The end of the pivoted lever b carrying the lever01 and connected mechanism, is normally pressed by the spring 9 againstthe stop h which serves to limit its upward movement.

D is the synchronizing wheel of the clock, and E the synchronizing leverhaving the toe e to enter the notch d in the wheel D to synchronize theclock. The lever E is pivoted att' and is normally held out ofengagement with the wheel D- by the spring j. A back stop It serves tolimit the movement of the lever E. The synchronizing lever is providedwith a cam or projection Z which extends into the path ofthe pivotedlever d, or the cam may be omitted and the lever 02 be allowed to strikethe synchronizing lever to move it.

The circuit connections are as follows: From a controlling clock G bywire 10 to and through the synchronizing magnet O thence by wire ll tothe motor A and by wire 12 to the battery 14, and by wire 15 to theclock G. This clock G is provided with a circuit closer arranged to'sendat predetermined intervals over the circuit an impulse of severalseconds duration.

The detailed operation is as follows: The main spring contained in thegoing barrel B being first fully wound, the clock is set in motion, andcontinues to operate in the usual manner of clocks. At a predeterminedtime the controlling clock G closes the circuit and a current is sentover the line through the synchronizing magnet O and motor A. Upon thecompletion of the circuit by the clock G, the magnet O attracts itsarmature a and rocks the lever b. As the lever b moves the lever (1carried thereby will come in contact with the cam Z and rock the lever Eforcing the toe 6 into the notch d of the synchronizing wheel D andeffecting the synchronizing. 1

As the lever b continues to move the lever 01 will vpass ofi the end Zof the cam Z, and the spring j will snap the lever E back against itsstop and out of engagement with the synchronizing Wheel D, so thatduring the prolongation of the impulse the wheel D will be free torevolve. As long as the current continues to flow the magnet C willattract its armature a and hold the end of the lever b carrying theleverd depressed, and the lever 01 out of contact with the synchronizinglever. As the impulse comes over the line it will set the motor A inmotion to wind the clock spring. This impulseis prolonged for severalseconds in order to give the motor time to fully wind the clock for theamount that it has run down.

It will be understood that I may use a clock capable of running severaldays without rewinding, several of which may bein the same circuit, andsynchronize and rewind the same at intervals of a day or less, so thatin case of accident to a clock or the circuit, the clocks will continueto run for several days until the defect has been located and remedied.

When the current on line has ceased to flow, the motor A stops, and atthe same time, the magnetO is de-energized and the spring 9 rocks thepivoted lever 17 until it comes in contact with its stop h. As the lever12 is returned to its initial position, the lever cl comes in contactwith the cam or projection Z and is rocked thereby against the tensionof the springf until the lever d snaps past the end I. of the cam orprojection Z. The lever d is now returned against its stop a by thespring f. In order to prevent the toe of the synchronizing lever E frombeing again forced into the notch 6' should said notch be opposite thetoe while the lever b is returning to its initial position, the springjis made stiffer and of greater tension than the springf.

The described operation is repeated at predetermined times, as often asit is desired to synchronize and Wind the clocks in circuit.

I do not limit myself to any particular form or type of motor,synchronizer, or clock, as they may be greatly Varied without departingfrom the spirit of my said invention.

Having described my invention, What I claim, and desire to secure byLetters Patent, 15-- 1. The combination in a clock, of a synchronizinglever, a synchronizing magnet for actuating the same, an electricwinding mechanism and circuit connections for the magnet and windingmechanism, all arranged so that the clock maybe wound and synchronizedby the same electric impulse, substantially as described.

3. In a clock, an electric winding mechanism, a synchronizingelectro-magnet in circuit therewith, a synchronizing lever, andintermediate mechanism between the magnet and synchronizing leveradapted to actuate and release the said lever by one movement,substantially as described.

4. The combination with the magnet C, a synchronizing wheel D, of thepivoted armature lever b, the pivoted levers d and E, and means forrestoring the several levers to their initial positions, substantiallyas described.

5.
